We're dividing 521354 by 28 
Let's see how many times 28 fits into 521354.

Let's proceed to step 1:
If we divide 5 by 28, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 28

Step 2:
52 divided by 28 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 28 from 52 and we're left with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 28

Going ahead to step 3:
241 divided by 28 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 17 after subtracting 224 from 241.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 28

Advancing to step 4:
173 divided by 28 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 186.0
The remainder is 5 after subtracting 168 from 173.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 28

Moving on to step 5:
The number 28 fits into 55 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1861.0
Deduct 28 from 55 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 28

Moving on to step 6:
28 goes into 274 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 18619.0
Subtract 252 from 274 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
The number 28 fits into 220 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 18619.7
Subtract 196 from 220 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 18619.78
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 18619.785
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 18619.7857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 18619.78571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
28 goes into 120 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 18619.785714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 18619.7857142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18619.78571428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 18619.78571428 with a remainder of 1.6e-08.
